Improvement in plows



UNITED STATES PATENT EEIOEo JOHN w. LOWE, OE ASHLAND, OHIO.

IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 150,662, dated April21,1674; application filed January 31, 1874.

To all whom it may concern:

Be it known that I, JOHN W. LOWE, of Ashland, in the county of Ashlandand State of Ohio, have invented a new and valuable Improvement inFlows; and'I do hereby declare that the following is a full, clear, andexact description of the construction and operation of the same,reference being had to the annexed drawings, making a part of thisspecication, and to the letters and gures of reference marked thereon.

This invention has relation to turn-plows, and it consists in theconstruction of a plowstandard, as will be hereinafter more fullydescribed.

The following is a description of my improvements vIn the annexeddrawings, A designates the plow-beam B, the handles; (l, the moldboard,D, the land-side bar, and E the plowpoint. The stan dard consists of avertical portion, a, a forward inclined portion, al, and a rear curvedportion, b, which latter is slotted and notched, for a purposehereinafter ex.- plained. The front inclined portion al of the standardis beveled to a sharp edge, and constructed with a laterally-inclinedwing, a2., which affords a firm bearing for the moldboard O just abovethe share F. The front edges ofthe mold-board and land-side are beveledto sharp edges, which are adjusted into a V-shaped groove, c, formed inthe rear edge of the plow-point E. This brings the landside of the pointE iiush with the land-side bar I), and allows me to secure this bar, themold-board, and the point E rigidly together by bolts z' t', passedobliquely through them. I also extend the mold-board side of the point Ewell up and over the mold-board, and thus have a removable cutting-edgeon the point E. The share F is secured beneath the moldboard, and itsfront beveled end is fitted into the groove c in the point c, as shownin Fig. 3. This share is provided with two rows of holes, which allow itto be adjusted as it is worn away. The front ends of the two handles Bare beveled and secured together, and connected to the mold-board andstandard by means of a pivot, d. In rear of this pivot l the right-handhandle B is secured to the slotted portion b of the standard by means ofa beveled T-headed bolt, g, and a nut; and the left-han d handle B issecured to a slotted plate, b", which is bolted to the inner side of themold-board by means of a T-headed bolt, gf, and a nut. The slots throughwhich bolts g g pass are arcs vof circles concentric to the axis of thepivot d. Consequently, by loosening the said nuts the handles B B can beadjusted up or down to suit the height of the plowrnan. At the rearportion of the landside bar, and at or near its lower edge, I secure aiin or cutter, h, which will cnt under each succeeding sod, and keep theplow steady and down to its work. This cutter h will also aid the sharein the performance of its duty, and is especially useful in land wherethere are many root-s. The curved extension b of the standard will serveas a brace for 'the rear portion of the land-side bar, to which thecutter h is secured, and sustain this bar against the lateral strain O11it produced by the cutter. The colter G is secured to the beam A bymeans of a staple, p, and two lipped plates, a u, by removing one ofwhich the colter can be detached from its beam, or adjusted higher orlower. The notches in the front edge of the colter prevent it fromslipping'.

IVhat I claim as new, and desire to secure by-Letters Patent, is-

A plow-standard composed of the vertical portion a., forward inclinedportion al, having a laterallyinclined wing, a2, and the rear curvedportion b, having Vslot and adjustingnotches, substantially as shown anddescribed.

In testimony that I claim the above I have hereunto subscribed my nainein the presence of two witnesses.
